Endocrine I Flashcards
adenohypophysis vs neurohypophysis hormones
Adenohypophysis = GH, PRL, ACTH, TSH, gonadotropins
Neurohypophysis = ADH, oxytocin
hormone that stimulates all cells for growth and repair
GH
hormone that stimulates production of breast milk
prolactin (PRL)
hormone that stimulates adrenal gland to produce cortisol
ACTH
hormone that stimulates thyroid to produce thyroxine
TSH
hormones that control reproductive functioning and sexual characteristics, stimulate ovaries to produce estrogen and progesterone/testes to produce testosterone and sperm
gonadotropins
Neurohypophysis hormones are made in the _______ and transported into _______.
hypothalamus / neurosecretory granules
hormone that controls the blood fluid and mineral levels in the body by affecting water retention by the kidneys
ADH (vasopressin)
hormone responsible for contractions and breast milk production
oxytocin
Name the pituitary gland abnormality: failure or decreased production of GH
pituitary dwarfism
Name the pituitary gland abnormality: lack of response to GH
pituitary dwarfism
Name the pituitary gland abnormality: short stature, small jaws and teeth
pituitary dwarfism
treatment for pituitary dwarfism
human growth hormone replacement therapy
benign neoplasm of the anterior pituitary
pituitary adenoma
Name the pituitary gland abnormality: circumscribed mass in the sella turcica
pituitary adenoma
Pituitary adenomas are more common in _____ between the ages _____.
men / 20-50
Two types of pituitary adenomas:
macroadenoma
microadenoma
Macroadenoma or microadenoma? large, functioning adenoma
macro
Macroadenoma or microadenoma? associated with excess secretion of pituitary hormones
macro
Macroadenoma or microadenoma? cause a mass effect due to the size of the lesion
macro
Macroadenoma or microadenoma? may impinge on optic chiasm, leads to loss of vision
macro
Macroadenoma or microadenoma? invasion of the cavernous sinuses (oculomotor palsies)
macro
Macroadenoma or microadenoma? severe headaches
macro
Macroadenoma or microadenoma? small, nonfunctioning adenoma
micro
